In our setup the email outgoing IP (the Pmg, latest version) is different from the incoming mail IP (which is haproxy, that then has the Pmg as backend).
I guess it is not an issue to have two different IPs since so many email server work this way, but we see our outgoing mail failing the...
I am extremely perplexed by these error notifications I am receiving from my Mailgateway.
This email address (email@example.com), which does not exist, is involved somehow and I am confused where it is coming from, and why I keep finding it in all domains outgoing and incoming email...
ich habe hier das Problem das 2-3 meiner Linux Server Mails zeitweise keine Verbindung zum Proxmox Mail Gateway bekommen um Mails zu verschicken.

Two stupid questions.
1. Can I set different smtp helo name and smtp banner for each email domain filtered by PMG?
2. Can PMG send a Delivery Status Notification (DSN) message?
Having a few possibly concerning logs on my host, I appear to be getting some random connections made to Postfix. I currently have it set up to "Internet" as I have an SMTP server elsewhere

Hey all, new to proxmox, so please forgive me my basic questions. I use proxmox on my home-server, so no professional use here. I have one thing left to...
Longtime PVE user here! I have used Proxmox since mid 2013 for private use, and just recently deployed a couple of Enterprise ones at various companies.
I realized that it would be very neat if I during installation or in the WebUI could provide SMTP credentials (SMTP-host...
I am running into some issues sending mail and was hoping someone may be able to assist. From what I can tell PMG is sending mail externally exclusively on port 25. I am trying to change it to 587 as my ISP blocks port 25. I have attached an image for your reference. Any assistance would...
I'm trying something with PMG. What I want to accomplish, is that I can sent mails from different hosts in different public networks on the internet via PMG acting as a SMTP relay.
The problem is, that these hosts on the internet are in networks with dynamic public IP's. So I can't at these...
When we use the final action 'Block' in the rules, the following happens:
